Abstract: Alliances are strategic assets that safeguard the national security interests and hegemony of the United States. Since the United States began its competitive strategy towards China, it has intended to form a strategic deterrence against China through the alliance of the trilateral relationship between the United States, Japan, and ROK, in order to win over China. The United States, Japan, and ROK have jointly taken a series of strategic measures, not only provoking ideological “factional confrontation” with China in terms of values, but also forming a “small NATO” in Northeast Asia to contain China in terms of military security, and promoting the “de-sinicization” of Chinas supply chain in economic cooperation. However, at the same time, the alliance of the trilateral relationship between the United States, Japan, and ROK also faces constraints such as goals beyond the scope of the U.S. financial resources, a lack of deep reconciliation in Japan-ROK relation, and potential checks and balances from China, Russia, and Democratic Peoples Republic of Korea. Therefore, in order to eliminate the small group pressure brought by the alliance of the United States, Japan, and Republic of Korea, China needs to continuously balance the strategic stability relationship between China, the United States, and Russia in Northeast Asia with the development of the international situation, actively promote economic cooperation with Northeast Asian countries, especially Japan and Republic of Korea, and thus promote the construction of a community with a shared future in the surrounding areas to jointly create a new future for Asia.

Key words: the U.S.-Japan alliance, the U.S.-ROK alliance, trilateral relations, alliance-building
